Picture the scene, it's a Tuesday evening at the Novello Theatre just off the Strand and I am sat between Ronnie Corbett and Andrew Scott (Moriarty from Sherlock). Dotted around us are the American from Downton, a man from War Horse, Patricia Routledge and Olivia Coleman. It could not have turned out better.
Although I am reliably told it is a 'classic', before I saw the new West End revival, the only things I knew about Sweeney Todd were the two words 'Sweeney' and 'Todd'. I was the proverbial blank canvas going into the performance - I didn't know what to expect, what the story was, what the music was like: nothing.
